Definitions

  • the invention relates to a push button device for a larger, multiple contacts covering key according to the preamble of claim 1.
  • Such a push button is disclosed in DE 33 29 698 A1, where it says: Individual Pushbuttons on typing keyboards are much larger than the other keys and large compared to the contact to be actuated.
  • To tilt in the case of off-center Avoid actuation are as a guide between the movable and the immovable button part provided two scissors. Their two axes are mutually related kept aligned.
  • the four bearing points of the upper free ends of the arms enclose a rectangular area that largely coincides with the operating area.
  • buttons are immovable on the Base plate arranged touch parts lifted off and put back on so that a other contact is activated.
  • the entry area of the Guide slots deformed and the entire facility become unusable.
  • the invention is therefore based on the object in a generic Push button device to find measures with which a deformation of the guide slot are avoided and in addition easier installation is possible.
  • Fig. 1 shows a view of a keypad 1 with 4 contacts 2 by a single large button 3 is to be covered, e.g. only one switching cam (not shown) having.
  • a contact 2 can now be selected by turning the button 3, which is intended for a specific function.
  • the device has a scissor device 4, the between the movable button 3 and immovable, arranged on a base plate 5 Key parts 6 is made.
  • the scissor device 4 has guide pins 8 on scissor arms 7 on in the guide slots 9 of the button 3 and in guide slots 10 of the immovable Key parts 6 are stored.
  • the scissor device 4 ensures that when the button 3 is pressed off-center, the other areas are taken parallel, so that key 3 is not tilted.
  • the switching behavior of the contact 2 is determined by the guide device 4 not affected.
  • the guide slots 10 in the immovably arranged button parts 6 can be used as closed guide slot 10 are executed, as in Fig. 3 left, uncut is shown since the guide pin 8 in any position to the guide slot 10 in these after overcoming the guide slot wall 12, as shown in FIG. 4, can snap into place.
  • the Scissor device 4 is composed of two identical frame parts 13, wherein each pair of scissors arms is connected in an axle bearing 14 shown in FIG an axle 15 of one frame part 13 and an axle bearing hole 16 of the other exists and is secured in the axial direction by a clip 17 of the pin 15. As a result, easy assembly of the scissor device 4 has become possible.
  • a frame part is shown as an individual part
  • the resilient property of the scissor arms 7 by a U-shaped design of the frame parts 13 can be reached, possibly with a frame wall 18 in the central region, as in dash-dotted lines is shown, or can be achieved by a U-shaped frame loop 19, also shown in dash-dotted lines.
  • Frame wall 18 or frame loop 19 increase the Torsional rigidity of the frame part 13 without the spring action of the scissor arms 7 diminish excessively.
